Landsat Maps Global Surface Water and its Long-Term Changes

You are here

Brown Marsh in southeastern Terrebonne Basin, Louisiana A partnership between the European Commission's Joint Research Centre and Google Earth Engine has yielded a new online interactive mapping tool that highlights changes in Earth's surface water over the past 32 years. The Global Surface Water Explorer, which consists of 3 million Landsat images collected over the last 32 years, shows that impacts on surface water occurrence can come from a variety of factors.

The information contained in this tool will improve additional surface modeling, help to mitigate flooding, and improve global policies and water-management decision making. The Global Surface Water Explorer tool is available to everyone at no charge.

Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
